Hi John Walliker; In answer to your questions: (1) What makes you so sure these things (high cost, difficult manufacturing, reliability issues, lack of price/performance) will not happen with DDR, especially when one attempts to scale the speed much higher? High cost has already been proved wrong, as noted in the reply a couple before this by me. Difficult manufacturing in RDRAM was the consequence of Intel and Rambus telling other companies how to make their boards and chips. DDR is those companies agreeing to make their boards and chips to a standard. I believe that it is quite obvious that the board and memory chip makers know their business better than Intel and Rambus, and this has been proven out. Reliablility issues in RDRAM were a consequence of excessively tight tolerances. (Thereby creating a design that is intolerant of small manufacturing deviations.) DDR doesn't use those tight tolerances, the frequencies are much, much lower, so they are not needed. Sure reliability could suffer in the future if someone screws something up, but isn't that getting kind of speculative? Price/Performance has already been proven in the graphics industry. Our disagreements on this probably are mostly on price, and the above link covers this issue. In short, DDR is already shipping cheaply in graphics cards, why should the narrower width chips cost a lot more in memory cards? -- Carl

Hi John Walliker; Re Intel's current difficulties Intel's current difficulty is a resurgent AMD. Take a look at the AMD price. Watch the earnings announcement this week. Re the MVP3 chip set. It isn't being used because it was before its time. Machines at that time really had no need for the faster bandwidths DDR provided. RDRAM is claiming to have the same trouble even now, when they suggest that future processors will make the technology look much better, while current processors don't show much advantage. Imagine what it would be like if RDRAM had hit the motherboard market 2 or 3 years ago. -- Carl
